Hi, I am new to Cathe and to the forum. I found Cathe through Tom Venuto’s forum. Thank you to all of you who have posted there which lead me here. I have been looking for a weight lifting (dvd) program for a long time. I ordered STS, it should arrive early in the week; in the meantime I am assembling my equipment, and looking at the 1RM tests on the workout manager. I do have a simple question though,. I have inherited two stability balls, one green at 65cm and one blue at 75cm. I am 5’4” weigh 118#’s, are the blue and green balls too big? Would the pink ball work (at 55cm) work best for me? I haven’t used stability balls in any of my workouts, so I am not sure what the advantages or limitations are of the various sizes. Thanks for any input you can give. I plan on start Meso1 Disc 1 on 4/18 if anyone would like to join me! Janis
